Cookies, and the one thing we use them for

No advertising or cross-site tracking. We store your answer and a few settings the tools need. Google Analytics — anonymous visit counts — stays off unless you switch it on.

  • Always on

    Remembers your answer to this notice, your accessibility settings and an open chat, and lets the contact form block spam. No tracking, and it cannot be switched off.

  • Google Analytics 4: counts of which pages and tools get used, so we know what to improve. It sets two first-party cookies and is not loaded at all unless this is on. No advertising, no audiences and no cross-site tracking either way.
